To all whom t may concern.'

Be it known that I, ANTON J. HAUG, a citizen of the United States, anda resident of Nashua, county of Hillsborough, State of New Hampshire, Whose post-office address is Improved Paper Machinery Company,

. Nashua, New Hampshire, have invented an Improvement in Machines for and Processes of Working Paper-Stock, of which the fol-A lowing description, in connection with the vaccompanying drawings, is a specification,

like characters'on the drawings representing like parts.

This invention relates to machines for and process of working 4paper stock and has for its object the provision of improved methods and appliances which may be employed either in preparing the crude pulp -from raw material or in working the crude pulp into a more refined state.

The invention will be best understood by reference to the following description, taken vin connection with the accompanying illustration of one specific embodiment thereof, while its scope will bemore particularly pointed out in the appended claims.

ple, as more or less unreduced librous material or pulp reduced to a more or less crude state. e y

Referring to the machine illustra-ted in the drawings, the same includes a body or casing, herein in the form of a cylindrical shell 6, supportedV upon) bed'pieces 7, the latter resting on the bed plate 8. The casing herein rests in thebed pieces 7 and is ixedly secured therein by the bolts9, but, if desired, the casing might have a movement of rotation either'with or without the rotation of the rolls, hereinafter referred to.

Herein the stock is introduced at one end of the casing through the inlet .passage 10` and is progressively advanced through the sameto the discharge chamber 11 and the discharge spout 12, after Vbeing subjected to a succession of crushing and rolling actions.

On its movement through the casing, the stock is subjected to a succession of crushing actions, preferably by means of rolls, the rolls being' preferably though not necessarily arranged so thata true crushing action -is obtained without any substantial grinding or abrasive action. While various devices might be employed for this purpose, herein there are provided one or more rolls extend ing lengthwise the cylinder and adapted: to bear against the inner face'or surface of the cylinder, the rolls being carried around the inside of the cylinder l'by suitable rotary sisting of the rolls 13 and 14 arranged diametrically opposite each other and the other pair consisting'of therolls 15 and 1GL also.A

arranged'diametrically opposite each other, degrees apart away from the rolls 13"'and 14.

All four rolls are mounted lupon shafts which have their` ends journaled in boxes carried in thespiders` 17 and 'Each spider in turn 1s keyed to the shaft- .Ifilthe 21 and being provided at one end with theiiy wheel 22 and at the opposite end with the driving pulley 23. To support the bearingl,r boxes i'or the rolls, each spider has bolted on the inside of its flange 4r guides 24 adapted to receive and liruide the bearing),F boxes QT), which. latter receive the shaft ends '26 for the rolls. The bearing boxes are adapted to move radially outward or inward in their guides as indicated in Fig. fi, but arenon mally pressed outward by the ysprings 27. The result is that, as .thelspiders 17 and 1S are rotated through the driving shaft, the rolls are Forced into rolling contact with the inner surface of the cylindrical shell both by centrifugal action and by the action of the springs 9.7, while the springs Q7 permit the required yielding n'iovement of the rolls and also hold theni in position when the ina chine is at rest. @While the rolls themselves might be independently driven, herein no further rotating agency is shown than the rolling contact of the rolls upon the 'face of the cylinder and the .stock passing thereunder as the spiders are turned` the rolls being pressed outwardly by centrifugal force their pressure increases with the speed oi? the machine, so that the crushing action oi the machine may itseli be regulated by varying' the sl'ieed.

The rolls 15 and 1G intermediate the rolls 13 and 14 are herein shown as extending; part way only `across the cylinder and located near the outlet end thereof, so that they act upon that portion of the steelt 1 which has already been partly disintegrated,

crushed or refined. As the coarse materials enter the inlet of the machine they will tend to lift the rolls which they encounter and force them away from the surface' of the cylinder more or less, By providing' the in tcrniediate rolls 'which enga only the more refined portions of the stock, such rolls are not subjected to the same degree of lifting action as the rolls 13 and 14, and the stock in the course of its travel through the ina-- chine and as it becomes more highly refined may thus be subjected not only to an increased rolling. action, but one ot greater intensity through the medium of the intermediate rolls 15 and 16, Workingas they do in closer contact with the surface of the cylinder.

The machine illustrated is preferably a continuously fed machine, the stock being continuously vfed thiough the inlet 10, advancedprogressively through the machine and continuously delivered `From the outlet 12. In order progressively to advance the stock through the machine between each crushing action of the successive rolls, suitable feeding devices are preferably employed. y

These may be of any suitable type, but here-- in I 'have shown secured to the driving; shaft 119 a series of devices which torni, in effect,

a screw conveyor acting to convey the material fromv one end of the machine to the other While subjecting it to the repeated crushingr actions.

and 3) suitably eut `array to avoid interi eure with the rolls 13 and iet and vith the shafts 2G ior the rolls and 16, these venes being forincd in. nts, each unit being mounted on a huh and the hubs non rotatably secured to the driving;1 shaft El. ett similar units are employed for the last halt ot the cylinder except that the Yanes 31 are 'lnrlher cut away to avoid interiierenee with the rolls 151 and 16. ine cylin der near its inlet end is pari closed by the end ringr or rap piece 32 uf'liieb prevents the escape or oif'ei'liow oi stock. I

The action oi" the niarliine on the sto-cir to liig. 5, the stort; on entering is subjected o the crushing' action oi the roll luf-. lln'ierg" ingr from beneath the roll 13 it engaged by the approva-,liingI part oi? the vane 29 which acts not only progressively to advance the material lengthwise the cylinder before delivery to the next roll l-i, but also to scrape up and agitato the material in its z""'eiied, sheet-like Yforni and heap it up n front ot the roll 1l in the torni of a relaii'ely thiclieiied stream. '.llhe material is lieu :igl'ain rolled and crushed by the roll 14. and the saine aetiini follows in the ronvcyanco oi" the material lfrom the roll 14 to the roll 13 as it did in its conveyance from the roll 1253 to the roll 1l. This action is re peated over and over again as the material is progressively advanced alone; the cylinder until it reaches the radius of action or" the rolls 15 and 1G. :tt that point the material delivered to the roll is conveyed to the interii'iediate roll 15 before passing; to the. roll 1li, and the i i conveyed beneath the agjain to the roll 13.

.it will beobserved that the conveying devices progressively advance 'the steelt be neath successive portions of the rolls so that the saine stock meets the same roll always at an advanced position lengthwise the roll, and there is at all times an even distribution oi the sieri( over the inner surface of the cylinder which is beine progressively fed, through the cylu i if desired, the cylin der as Well as tne rolls may be rev lved,

roll lil heitere passing ,thereby roviding for an even Wearing of y a i nater'a' leaving the roll 14% Preferably the rolling oft the stock is accomplished as herein by aI true rolling action without any substantial abrading or Ygrinding action, so that the stock is reduced or refined by a crushing action and Without cutting, abrading or otherwise injuring the fibers.

It will be obvious that various other agencies and appliances maybe employed for producing the crushing or rolling action herein described, and that the invention is not limited to the number, form or construction of the crushing agencies 0r the shape or arrangement of the body or casing of the apparatus or to the respective location of the crushing agencies or their relative or tion.

actual movements, but that various modi'- hcations and forms and arrangement of parte may be employed without departing from the spirit of the invention.I i'
